I built my first PC a few months back. (Asus P45 motherboard, Intel 2 quad core processor, HD4850 graphics card, LG blue ray burner/player, Windows Vista 64 bit Home Premium). Initially I installed the HD4850 graphics card with default windows drivers. (I do not recall installing the Catalyst software or using the ATI drivers disk & Catalyst was not loaded.) It seemed to work fine and I had no problems with playing a Blu Ray disk using PowerDVD ultra on the player I have. Recently, however, I updated the HD4850 drivers and Catalyst software with the drivers that came on the CD. I also updated the latest Blu ray drive firmware. Ever since, I have not been able to play either of the Blu ray disks I have. It appears to play for a few minutes and then locks up. I have tried a different Blu ray player program. I have also tried to update the HD4850 drivers and earlier HD4850 drivers as well, but still having the same problem. Unfortunately, I can not roll back to the previous driver.
Has anyone had this problem? Is it a problem with the ATI drivers or Catalyst program? Is there a way to remove the Catalyst program and use default Windows vista drivers? Any help is appreciated.
